You guys ask and we deliver, so here are the results:

Vehicle Specs (before 3.5" TB):

2007 SS/SC
GM Stage 2 with 3" pulley
GM Honed manifold
GM Cat back exhaust
Rebel 3" Stainless Intake

Below you will see the before and after, the blue lines are before and red after.

Summary: Down low (3350rpm) we produced 11WTQ and 7WHP
Mid range (4000rpm) we produced 8WTQ and 6WHP
Top end (6000rpm) we produced 12WTQ and 14WHP

Notes:

1. The only thing changed in the tune was the idle air flow ETC scaler area, no fueling or spark settings were changed.

2. The install as you can see took less than 24 minutes as you can see the dyno runs are 24 minutes apart.

3. With the above mods (before the new TB) we only produced 219WHP showing how our dyno reads lower numbers. But the beauty of it is the difference is accurate. Now compare this to the Twin Screw numbers 281WHP produced on the same dyno in the middle of summer (hotter temps).

4. The air/fuel went low 10's after 6000rpm which we expect from the GM Tune. There is plenty more power to be made here with some tuning.
People who have installed this upgrade:

"ok so i got this tb upgrade done today. i can now attest to this being an AWESOME F'ING UPGRADE! we dynoed somewhere from 10-15whp gain in the lower rpm range (below 3G) and somewhere from 10-20 lb ft gains. this isn't one of those mods where you find yourself debating whether you actually feel any difference either. you notice the difference right away. it pulls much harder and much sooner on the low end and this is exactly what the cobalt needed because it was lacking on the low end. now it feels awesome! i'm so glad i did this and i give much props to rebel for another fine upgrade! cheers guys!"

"ill tell you right now throttle response in like no other cobalt ive driven b4 with the stock charger. its almost impossible to drive this thing slow since no matter what rpm you are in a slight touch of the gas the the car darts forward, first gear is that much more usless now lol. stomp in any gear and it pulls alot harder than what it was liek b4 all the way to redline. its a amazing mod to compliment all the other modifications i have to my car."


The 3.5" TB and spacer GB will end tomorrow!

Data Log Results:

Without New TB:

Boost 15.47 PSI
MAF 31.57 LB/MIN

With New TB:

Boost 15.62 PSI
MAF 31.57 LB/MIN

So basically you don't see much of a difference top end in flow numbers.

i think they are trying to say that you see a lot more low end torque, not so much max torque. which is really good considering our low end torque isnt that great.

Onyxd04Redline

While may be worth it to some it wouldn't be worth it to me. Nice work tho

r0k0

nice.. cant wait to put this in my car..!

the tb will only be on the spring tho.. but cant wait

joselo6

Can you slap a 2.9" pulley, tune and then give us the dyno numbers?

Eddie

nice expected some low mid range power increase and not so much max power. nice very nice. if i had the money i would so go for this.

Eng@RebelAutoWorxs

maybe in the near future, got too many other projects on the go.

But I'm sure with the ones going out this coming week, we will see a lot of results and different setups

R&C_rallySS

Yea after looking closer I can see the gains now. WTF was I thinking I don't know. Thats not to bad of a gain. Is it to late to get into this GB?

joselo6

Would it be safe to install this 3.5 tb with stage 2 and a 2.9 pulley without a tune?

Area47

you can take my spot on the list if you like.

IamTvor

Just PM when I need to pay.
